This pillow is designed for babies aged 6 to 18 months to create a perfect head shape.The center of it is a head fossa concave area gently supporting the back of the head. The head fossa area employs a combination of triangular mechanical balance and semi-circular design. The application of the professional theory of anatomical positioning of babies' heads and necks is beneficial for cranial development and neck blood circulation. The outer side sleeping area is widened and designed with a circle of ear grooves to prevent babies' ear bones from being squeezed by the pillow surface when sleeping on the side at multiple angles.
